The three core elements of meet- ing these regulations are: I) Electronics, ADEM A4; II) Fuel delivery, Mechanical-activated Electronic Unit Injection (MEUI); III) Air Management, Wastegate Turbocharging, Air to Air Aftercooling (ATAAC) with the proven technology of a crossflow cylinder head. ● Cat electronically controlled transmissions … Transmissions purpose built and designed for articulated trucks and their applications. Electronic controls provide complete integration with the engines for smooth shifting and efficient power delivery as well as offering advanced diagnostics and trouble shooting capabilities. ● Articulating and fully oscillating hitch … Links front and rear frames for exceptional maneu- verability and traction on uneven terrain while elim- inating damaging twisting of the frames. Bolted hitch design allows optimum material choices for the cast hitch head and the hard-wearing tube. Bolted design allows easier rebuild and repair. ● Three-point front suspension … Three-point front suspension with long-stroke, low-pressure suspension cylinders provide unparalleled ride quality for operator comfort and higher average haul speeds. Front and rear suspension together with the hitch provide for excellent traction in all conditions. ● Wide, long and low dump body design … For excellent loadability and high fill factors, excel- lent machine stability and load retention as well as a good match for other Cat loading systems. Diverging flow design also gives excellent mate- rial ejection. ● Standard ROPS/FOPS, low sound level cab … Two man cab common across the range. Large cab with excellent all around visibility, ergonomic control layout and plentiful storage. ● High capacity low pressure tires in single formation … For superior traction and flotation in poor underfoot conditions. 10 ARTICULATED TRUCKS

Use of Ground Pressure ChartsArticulated trucks are normally equipped with
wide base radial tires, for improved flotation in poorunderfoot conditions. Ground pressure is a functionof tire deflection and is also affected by tire pene-tration. The charts in this section provide a meansto estimate ground pressure for 0 and 76 mm (3")tire penetration, when gross vehicle weight, axleload distribution and tire inflation pressure areknown. The ground pressure charts on the followingpages are based on Michelin XADN tire character-istics. Results may differ for other tread patterns.
Tire load can be calculated by the following formula:
Heaviest Axle LoadTire load = __________________

Example
Find the ground pressure generated by a 725 fullyloaded with zero and 76 mm (3") tire penetration.The machine is equipped with standard Michelin23.5R25 tires, inflated to the recommended pressure.
43 680 kg � 0.34725 Tire Load = ________________ = 7426 kg
